Find a. $\left(\frac{\partial w}{\partial x}\right)_{y}$$\quad$ b. $\left(\frac{\partial w}{\partial z}\right)_{y}$ at the point $(x, y, z)=(0,1, \pi)$ if $w=x^{2}+y^{2}+z^{2}$ and $y \sin z+z \sin x=0$

Key Concepts

Evaluation of Derivatives at a Specific Point

Evaluating derivatives at a specific point involves substituting the numerical values of the variables into the derived expression for the derivative. This step yields the exact rate of change at that point and is crucial for obtaining concrete numerical answers in applied problems.

Implicit Differentiation

Implicit differentiation is used when the relationship between variables is given by an equation where the dependent variable is not isolated on one side. This technique differentiates both sides of the equation with respect to a particular variable, treating other variables as functions of that variable when necessary, and is especially useful when a constraint couples the variables.

Partial Differentiation

Partial differentiation is the process of finding the derivative of a function with multiple variables with respect to one variable while holding the other variables constant. It is a foundational concept in multivariable calculus that allows analysis of the sensitivity of a function to changes in one of its inputs independently of the others.

Chain Rule

The chain rule is a fundamental method for differentiating composite functions. In the context of implicit differentiation, it allows us to account for the fact that one variable may depend on another, by differentiating the outer function and then multiplying by the derivative of the inner function.
